Van keeps coming in on back of recovery truck as a none starter...when you plug Dec ss3 in.you notice no keys programmed.and no chassis number programme ..once you program keys and chassis number.van starts and keeps running for about a month then the same happens.
I thought that once the chip in the bsi was programmed..is shouldn't loose it memory...
Any ideas what would cause this..

Hi

Get a few of these- 307s as well

Usually caused by voltage issues- jump start etc

just double check no water ingress to Bsi also

Mark

Thanks mark...bsi is bone dry.no corrosion at all...Van can be OK. Park it up..come to start it next day and it happens with out jumping it...nobody touches it and it happens

Hi

Its looking like KAM in bsi is failing

Dont know how you can prove without changing it

Mark

Hi mark...would this just be a single chip that needs changing by a specialist ..or a complete bsi

i have been down the road of Bsi repair..... it nearly always ends up having a new unit fitted
